A young woman is giving her menstrual history to the nurse. She is concerned about a short-lived pain that sometimes occurs on either the right or left side of her lower abdomen about 2 weeks before her period is due to begin. What is the nurse’s best response?
- A. “This pain is probably related to ovulation and is not uncommon.â€
- B. “The pain may be caused by abnormal hormone levels, so the levels should be checked.â€
- C. “Don’t worry, this is to be expected in young women.â€
- D. “There might be some structural abnormality that should be assessed further.â€
Correct Answer: A
Rationale: The correct answer is A: "This pain is probably related to ovulation and is not uncommon." This response is the best because the pain described by the young woman aligns with symptoms of ovulation pain, known as mittelschmerz. This type of pain typically occurs around the time of ovulation and is considered normal. It is a common experience for many women and does not usually indicate any underlying health issues.
Choice B is incorrect because abnormal hormone levels are not typically the cause of ovulation pain. Choice C is incorrect as dismissing the woman's concerns without providing reassurance or information is not appropriate. Choice D is incorrect as there is no indication from the history provided that there is a structural abnormality that needs further assessment.
In summary, the correct response acknowledges the normalcy of the pain experienced by the young woman and provides reassurance based on the symptoms described.
The olfactory nerves go through the ______ to enter the cranial cavity:
- A. Foramen ovale
- B. Cribriform plate
- C. Foramen spinosum
- D. Superior orbital fissure
Correct Answer: B
Rationale: The correct answer is B: Cribriform plate. The olfactory nerves pass through the cribriform plate, which is a part of the ethmoid bone located in the anterior cranial fossa. This structure contains numerous small perforations that allow the olfactory nerve fibers to pass through and enter the cranial cavity, specifically the olfactory bulb. The other choices, A, C, and D, are incorrect because the foramen ovale is located in the sphenoid bone and transmits the mandibular nerve, the foramen spinosum transmits the middle meningeal artery, and the superior orbital fissure transmits structures like the oculomotor nerve, trochlear nerve, and ophthalmic nerve, but not the olfactory nerves.

While performing a self-breast exam, the patient notes an area on the right breast that is nodular, with some associated tenderness. This is a new onset finding because the exams were
- A. The patient calls to report her findings to the clinical nurse because this is not her typical result. What action should the nurse perform next?
- B. Refer the patient to an oncologist because the results are suspicious.
- C. Ask the patient to come in for an office visit so that the findings can be validated but tell her that this information is within the normal range of presentation.
- D. Have the patient wear a tight-fitting bra and tell her that the tenderness is associated with ovulation and will pass.
Correct Answer: A
Rationale: The correct answer is A because a new nodular area with tenderness in the breast is concerning for a potential breast abnormality or pathology. The nurse should advise the patient to report these findings promptly to a healthcare provider for further evaluation, which may include a clinical breast exam, imaging studies, and possibly a biopsy if warranted.
Choices B, C, and D are incorrect because B jumps to a conclusion without proper assessment or evaluation, C downplays the significance of the findings without proper validation, and D provides inaccurate information about the association of tenderness with ovulation, which is not relevant in this context.
